FFHZE ARTHUR J. SLINGERLAND, OF CHICAGO, ILLINOIS wmnow FASTENERApplication filed February 3, 1928. Seriahll'o. 251,619.

My invention relates to improvements in fastening devices, and itconsists in the combinations, constructions, and arrangements hereindescribed and claimed.

An object of my invention is to provide a fastening device wherein novelmeans is em-. ployed for. positively looking a window in any desiredposition. i

A further object of my invention is to provide a device of the typedescribed which has novel means for holding the window 1 Other objectsand advantages will appear 3 in the following specification, and thenovel features of the invention will be particularly pointed out in theappended claims.

My invention is illustrated in the accon1- panying drawings, formingpartof this ap- PllC2ttlO11,ll1 which Figure 1 is av longitudinalsectional view of p the window construction illustrating the novelfastening means, i Figure 2 is a front elevation of the windowconstruction. illustrating the fastening means, and

Figure 3 is a plan view of the fastening means shown inoperativeposition in solid lines and out of operative position in dotted lines. y

In carrying out my invention, I make use of a window frame 1having.longitudinally extending grooves 2 therein. A window. 8 isprovided with tongue portions 4; which are movably disposed in thegrooves 2.

I provide a corrugated fastening strip 5 rigidly secured to the frame 1at each end 3y means of screws 6 or the like. The fa s toning strip 5 isprovided with transversely 9 extending side port-ions 7. The fasteningstrip is also providedwith receiving grooves 8 and retainingshoulder-s9.

A fastener 10 is pivotally mounted at 11 upon the window 3 and isprovided with a hinge portion 12. A tension spring 13 is disi posedconcentric with the shaft 14 of the h1ngeport1on12. One end of thespring 13 bears against the base portion 15 of the fastener1 0, andtheother end bearsagainstthe movable portion 16. i i

The movable portion 16 is provided with an integrallip 17 at the outerextremity thereof whichtapers inwardly toconform to the generalcontourof the locking strip 5 in cross section. The IDOVitlilQPOltlOIl 1613also provlded with retaining cars 18 which are arranged to extend aroundthe edges of the locking strip for a purpose hereinafter described. Ahandle or knob 19 is provided for the movable portion 16. v

From the foregoing description of the various parts of the device, theoperation there of may be readily understood. Let us assume that thefastener 10 is in the position shown in solid lines. It is obvious thatthe tension spring 13- tends to force the movable member 16 into andhold it in close engagement with Ell thefastening strip 5. In so doing,the lip 17 is received in one of the recesses 8 and abuts the adjacentretaining shoulder 9. Therefore, any tendency to move the window 3upwardly with respect to the frame 1 would tend to more firmly force thelip 17 into locking engagement with the fastening strip 5.

The window 3 may be moved downwardly, I

and, in doing so, the lip 17 of the movable.

member 16 will ride over the retaining shoulders 9 until the movement ofthe window has ceased. Then, if the window is forced upwardly, the lip17 will be forced by the spring 13 into the adjacent recess 8 andagainst the adjacent shoulder 9. he retaining ears 18 extend upon eachside of the fastening strip 5 for holding the movable member againstlateral displacement. The cars 18 also hold the window against lateralmovement.

The fastener 10 may be freed from the fastening strip 5 by theoperatofisgripping the handle 19 and drawing the movable member lG free from thefastening strip.

WVhen the movable member 16 is freed from the fastening strip, the latchor lock 10 may be swung about the pivot 11 and allowed to remain in thedotted line position shown in Figure 3 out of engagement With thefastening strip. i

I claim: 1. A device of the type described comprising a fastening striphaving transversely extending side portions, a fastener, means forholding said fastener in engagement with said fastening strip, and earsintegral With said fastener and extending substantially'at right anglesWith respect thereto, said ears be- 15 ing adapted to be disposed uponeach side of said fastening strip and to engage With said side portionsirrespective of the movement of saidfastener With respect to saidfastening strip.

7 '2'0 2. A device of the type described comprising a fastening striphaving transversely extending side portions, a fastener, means forholding said fastener in engagement with said fastening strip, earsintegral With said fastener and extending substantially at right angleswith respect thereto, said ears being adapted to be disposed upon eachside of said fastening strip and to engage With said side portionsirrespective of the movement of said fastener With respect to saidfastening strip,

and means for pivotally supporting said fastener whereby said fastenermay be moved out of engagement With said fastening strip. Signed atChicago, in the county of Cook, and State of Illinois, this 31st day ofJanuary, A. D. 1928.
